Lincoln 2002 continetal 4.6 All codes have been fixed and new fuel pump car runs great a high speeds will idle well right at first. Then when you come to a stop may idle well for few seconds or minutes then rpm go up and down a little around 600rpm then die like you turn off key??? what would cause this??? pressure in fuel runs between 28 to 32lb and this is the one with elctronic fuel regulator. Also have replaced throttle positioner sensor and map valve. DAN

You may want to check for vacuum leaks, see if you notice any hissing sounds coming from the top of the engine area, look at the PCV valve & hose in particular.
You may also want to clean the throttle body, if it gets too dirty the comp can't raise the idle up enough any more via the IAC motor and you can get this problem.........
